C# Multiple Indexers

Question

Is it possible to have something like the following:

class C
{
    public Foo Foos[int i]
    {
        ...
    }

    public Bar Bars[int i]
    {
        .

If you're trying to do something like this:

var myClass = new MyClass();

Console.WriteLine(myClass.Foos[0]);
Console.WriteLine(myClass.Bars[0]);

then you need to define the indexers on the Foo and Bar classes themselves - i.e. put all the Foo objects inside Foos, and make Foos a type instance that supports indexing directly.

To demonstrate using arrays for the member properties (since they already support indexers):

public class C {
    private string[] foos = new string[] { "foo1", "foo2", "foo3" };
    private string[] bars = new string[] { "bar1", "bar2", "bar3" };
    public string[] Foos { get { return foos; } }
    public string[] Bars { get { return bars; } }
}

would allow you to say:

 C myThing = new C();
 Console.WriteLine(myThing.Foos[1]);
 Console.WriteLine(myThing.Bars[2]);
